Answers:
slope = 1.75
y intercept = 10
=======================================
Step-by-step explanation
y = 10 + 1.75x is the same as y = 1.75x + 10 since we can add two values in any order we want.
Compare y = 1.75x + 10 to y = mx+b
- m = 1.75 = slope
- b = 10 = y intercept
The slope of 1.75 means each time you add a topping, the cost increases by $1.75; in other words, each extra topping costs $1.75
The y intercept 10 means the base or starting cost is $10. This is the cost without any extra toppings. It's when you have x = 0 toppings.
We cannot use the slope formula m = (y2-y1)/(x2-x1) since we aren't given two points. Luckily the slope has been given to us.
